Used in pharmaceutical research as a key intermediate for developing central nervous system (CNS) agents, particularly in the synthesis of selective serotonin reuptake inhibitors (SSRIs) and related antidepressant compounds. Its structure supports high affinity for serotonin receptors, making it valuable in optimizing drug candidates for improved efficacy and reduced side effects.

Commonly employed in medicinal chemistry for structure-activity relationship (SAR) studies due to its chiral center and heterocyclic framework. Also utilized in the development of radiolabeled derivatives for receptor binding assays and neuroimaging applications.
